Correct option is C
Given:
Cost Price = ₹400
Profit by shopkeeper = 25%
Loss by buyer = 10%
Formula Used:
Selling Price with Profit = CP × (1+100Profit%)
Selling Price with Loss = CP × (1−100Loss%)
Solution:
First selling price (from shopkeeper to buyer):
SP1=400×(1+10025) =400×1.25=₹500
Second selling price (buyer to another at 10% loss):
SP2=500×(1−10010) =500×0.90=₹450
